SYSTEM DESIGN AND APPLICATION A PPLICATION ion ion In order to help understand the design design process, a typical typical example example hazard hazard is covered in this this section. There may be different design design approaches that that can be taken for any given hazard. The example is only intended to show show what has to to be done to complete the design and hydraulic calculations. Followingis an outline outline of the example example hazard. Each item is listed lis ted in the numerical numerical order in which it should should be performed. performed.

Control Room
Control rooms are found in all types of industry, housing transformers, motors. switch gear and other types of elec tronic devices necessary for energizing the various types of equipment.
ITEM NO. 2 - Design Calculation Sheet. Fill out the culation sheet with information required to determine total quantity of agentand percentof INERGEN agent c o n centration.
Protection of control rooms can be accomplished by treating it as a flood hazard in accordance with requirements of NFPA 2001, "Standard for Clean Agent F ire Extinguishing Systems."
ITEM NO. 3 - Preliminary Drawing. Complete a drawing or sketch as accurate as possible to determine pipe lengths and number of fittings. Locate and number all node points and nozzles.
The design of the INERGEN systemshould be in accordance with NFPA 2001, which states, "thedesign concentration must be achieved within 1 minute. It is important that an effective agent concentration not only be achieved, but shall be maintained for a sufficient period of time to allow effective emergency action by trained personnel. "
NO. 4- Flow Calculation Input Form. With the information on pipe lengths, fittings, node and nozzles, fill in the input form.
Personnel safety is the first concern. The INE RGEN sys tem should incorporate a discharge alarm andlor pre discharge alarm to warn personnel of a discharge. A time delay device is not needed due to the life supporting characteristics of INER GEN agent.
ITEM NO. 6 of Material. This should be generated to show the complete list of all required hardware.
ITEM NO. 5 -Computer Print Out. The computer print. out will compute discharge time. pipe sizes. union orifice size, and nozzle orifice sizes.
ITEM NO. 7 -Application Drawing. This application drawing is an example of the type of drawing which is generated from Ansul Application Engineering Department. This drawing is normally used to secure approval from the local authority.
Electrical power and ventilation must be shut down prior to system actuation. Common duct may require dampering to prevent INERGEN agent loss. Smoke detection
is
recommended.
The authority having jurisdiction may have additional re quirements.

No unclosable openings. Ventilation to be shut down at system actuation.
ITEM NO. 1 -Sketch of Hazard. Do an accurate sketch of the hazard area and measure all solid, permanent objects.
